To all whom it mag concern: 7

Be it known that I, JULIUS LARSEN, a subject of the King .of Denmarkfresiding at No. 13 Frederik den VIIGade, Copenhagen,

Denmark, have invented'certain new and useful Improvements in Pegging-Machln'es,

of which the following is a specification. v The present inventlon relates to a pegging machine, wh ch performs the pegging in a'manncr, str kingly resembling the hand pegging. By the pegging machines now generally used the awl and the hammer are forced downward either by the pressure from a strong spring or by the pressure executed by a track disk, the tracks of the disks being of such shape that the downward movement of the awl and the hammer partakes some-- what the character of a free drop.

The present invention differs from the inventions earlier known thereby, that for the movement of the awl and the hammer a single wheel shaped body only is used.

. For the movement of the hammer and the awl is used a track disk the groove of which is formed in such a manner, that the sledge which supports the revolver head and in which the awl and the hammer are mounted, may drop perfectly free. In order to 1ncrease the falling weight, the front end of the two-armed lever is made considerably heavier than the rear part. Besides the drop may be accelerated by special means. Thereby the peg is forced down into the hole, produced by the awl, 'by a hammer stroke which is like the strokes by which the shoe-maker drives inthe pegs.

Both the awl and the hammer are cylindric and the hollow peg guide is correspondingly formed and at the same time somewhat tapering.

The invention is shown on the drawing where Figure 1 shows the device seen from the side,

Fig. 2 the same seen in front, and

Fig. 3 shows one of the track disks seen" from the front.

On the drawing is shown a preferred 1 is the frame of shaft 4, whose one end carries a track disk 5, and the other end another track disk 6.

A N FF CE;

In the head 2 of the cylinder ismounted i ahorlizojntal shaft 7, upon which is fastened. 11

iZWQ swinging arms '8 and 9, of which the groove 57 in the track disk 5. Owing to the lattcrcarries afroller 10, which travels in a form of the trackth'e arm 9 and alsofthe arm 8 are oscillated by the'turning ofthe shaft f, and which in thej manner describedbelow is transferred to the revolver head 12.

20, embraced by a fork 15 on the revolver I The free end of the arm 8 hasa long" pivot head 12. The head is mounted on a pivot .on I the plunger 24, which travelsup and down in a pair of guides 25 inthe head. The head 12 carries an awl 13, and hammer 14,"

which by swinging in turn are brought in the vertical position.

For locking the revolve working positions, in which the awl 13 and the hammer 14 respectively are placedverti cally over the peg guide'16, the turning pivot 17 of tlie head 12 has 'a horizontal slot 18, in which is arranged a rod 19, which is pressed against the hub 21 of the head 12 by means of a spiral spring 22. In the hub 21 are two notches 23, with which the rod 19 engages, when the head 12 is in the two working positions. The upper end of the plunger 24:, which supports the revolver head, has a slot 26, through which the shaft 7 is passed, and the end of the plunger terminates in a head 29 below which the fork shaped end 30 of the double armed lever a Z) engages. The connection between the lever and plunger is such that the plunger r head in the two 7 I y 15 24 may slide some fractionsof an inch forward and'backward, and still remain in engagement with each other. v On the end Z2 ofthe double armed lever a Z) is mounted a roller'31, guided by a track ment of the plunger will, on account of its weight, have a free drop. "The drop may be accelerated by mounting a pair of rollers 28 on the fixed pivots 27 in'the track disk 6,

which by striking against the under side of the arm J) drives it upward with a quick stroke.

In order to get the pegs to keep better the peg guide 16 is provided with a somewhat conical guide canal 33 for the pegs, so that these under operation of the hammer 14;

' are pressed somewhat together when led through the canal.

It is to be understood that the peg guide with its operating parts is fixed on the head 2.

I claim:

1, In a pegging machine, a reciprocating plunger, a head loosely pivoted to the plunger and carrying an awl and a hammer,

power means for turning the head tobring V the 'awl and hammer alternately into vertical I position and automatic means for locking and releasing the head, said means being disengaged by the turning of thehead and engaged when the turning of the head ceases.

2. In a pegging machine, a slottedreciprocating'plunger, a forked head pivoted to the plunger and provided with an awl and a hammer, an oscillating shaft extending through the slot of the plunger, and an arm I on the end of the shaft and providedwith a pin engagingthe fork of the head. I

3. In a pegging machine, a vertically reciprocating slotted plunger, a head pivoted to the plunger, said head having a fork and provided with an awl and a hammer, a cam, a shaft extending through the slot of the plunger, an arm on the shaft and engaging the cam, and a second arm onthe shaft and provided with pin engaging the fork of the heads 7 4. In a pegging machine, a vertically reciprocating plunger having a slotted pivot pin, an oscillating awl and hammer head mounted on the pivot pin of theplunger and having a notched hub, a pin in the slot of the pivot; pin, and a spring onthe pivot pin and v pressing the pin into engagement with notches of the hub of the head.

5. In a pegging machine, a sliding plunger,

a lever pivoted intermediate of its ends and having one end engaging the plunger, a rotary shaft provided with two cams, with one of which'the said lever engages, a forked head pivoted to the plunger and carrying an awl'and a hammer, an oscillating shaft, an

arm on the said shaft and engaging the other cam of the rotary shaft, a second armon-the oscillating shaft and provided with a pin JULIUS LARSEN.
